OverviewThe film explores the notion that dogs are intelligent beings who arrived on Earth from outer space thousands of years ago to spy on humans. However, instead of reporting back to their home planet to aid in the preparation of a planetary invasion, the dogs remained, prompting Canid 3942 to come to Earth to investigate. Canid enlists the help of a boy who owns a dog walking service. The two must get the dogs in shape for an upcoming inspection. If the dogs fail the inspection, they must return to their home planet.
